Engage in whatever wordplay you want: reddit is a website built on community content and interaction. That there are user-created communities within the larger community does not turn it into some sort of "infrastructure" of internet expression. The infrastructure to build one's own site, and communities that go with it, are and should continue to be made available to all regardless of viewpoint. Given Voat's existence and the fact that people do use it, I do not see a problem.
